There's no doubt about it: Donuts are one wedding trend that's here to stay. Over the years, we've seen couples serve the traditional breakfast treat as a wedding cake alternative or addition, a coffee service garnish, a whimsical wedding favor, and more. In fact, whether raised or cake, glazed or filled, frosted or unfrosted, there are so many ways to make and display the diminutive dessert, we don't foresee it going stale anytime soon (pun intended). Plus, the convenient shape calls to mind another ring that's a mainstay in weddings.
